I Application filed June 7 1905. Serial Ho. 264.096.

To all whom, zit-may concern: I

Be it known that I, JOHN JORGENSON, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Locks, of which the followin is a specification.-

y invention relates to looks for the doors of residences and other buildings and for vaults and safes and for use generally wherever a lock is desired which cannot be opened except by some one possessing the and exact unlocking instrument.

The 0 ject of the present invention is to rovide a simple practical absolutely safe ock of the cylinder-knob variety which shall be comparatively chea to manufacture and which can be easily and instantly adjusted to operate with or without a key or set so it cannot be operated at all.

The invention consists of the parts and the construction and combination of parts, as

hereinafter more fully described and claimed, having reference to the accompanying drawings, in Which- Figure 1 is a horizontal section of my lock. Fig. 2 is a section on the line Y Y of Fig. 1.

v Fig. 3 is a section on the line X X of Fig. 1.

'Figs. 4 and 5 are perspective views of the component'parts of the housing. Fig. 6 is a perspective view of the tumbler-plate. Fig. 7 is a view of the ke Fig. 8 is a longitudinal section of the housing. Fig. 9 is a section on the line O O of Fig. 1.

A and B re resent respective inner and outer door-kno s, the outer one made hollow and integral with its hollow knob-shank and integral with its flange 2, which latter is secured to the outside of the door by means of the screws 3, which pass from the inside through the plate 4 and the door. The inner knob B is made integral with its knob-shank, and the latter has a limited reciprocatin movement in the plate 4 and is also capab e under certain circumstances of a rotative movement in said plate. A spring-pressed dog 5, carried by the inside knob-shank, is adapted to engage suitable notches or recesses in the bore of the late to hold the knob B from turning for t e purpose to be hereinafter described.

The part 6, by which the locking-bolt 7 is retracted, I pre er to term the latch member or actuator, and I shall so designate it hereinafter. This actuator takes the place of the roll-back of most locks and is designed to operate the bolt 7 by a sliding movement at right angles to bolt 7 rather than by any rotative movement of the actuator or of is adapted to be turned a quarter-turn or so at a time by depressing do 5 to permit the actuator to operate or to imit or entirely revent its actuation, as will be shown later. he bolt 7 is slidable and guided in a suitable sleeve 7 The actuator 6 is secured fast at one end to the shank of the inner knob B and in the same plane with the dog 5, and the portion of member 6 roximate to this shank is made slightly wi er than the shank and larger than the bore in plate 4 to form abutments 6 to engage against the side of the plate next to the door to prevent the reciprocation of knob B or the actuator except when this wider part of the actuator is brought into alinement with the 'diametricallyop osed notches 8 9 in the plate 4, and in whic notches the dog 5 is engageable. There is a third and shallower notch 11 located .between the notches 8 9 for the dog to catch in; but this notch is not sufliciently deep to let the actuator slide through plate 4. Between late 4 and flange 2 the member6 has a reduce portion 1 2, passing through and of such size and character as to be turnable in the slot 13 in bolt 7 A spring 14 keeps the latter normally projected outward to engage the keeper 15 on the door-jamb. This keeper 15 is preferred for its compact and neat appearance and simple construction. It comprises, essentially,.a flanged socketiece adapted to be set in flush with the sur ace of the jamb, secured in place simply by a screw 16, passed through a hole in the bottom of the socket and having a lateral extension or tongue 17 to lead the tapered end of the bolt 7 properly into the retaining-recess in the socket.

The actuator has two diametrically-opposed convergent cam-surfaces 18, connectmg with the portion 12 on the side of the latter adjacent to the outer knob. 14 always tends to press the rear wall 0 slot 13 (here shown as a pin 19) against the part 12 or 18 of the actuator. The outer end of the member 6 is so mounted in the outer knob-shank as to permit said member when the cams 18 are brought into the same lane with slot 13 to be reciprocated towar the inner side of the door to cause one or. the

other of these cams to engage the rear wall of either of the knobs, although the inner knob The s ring slot 13 and retract the bolt 7. The'end of the actuator corresponding to the outer knob is bifurcated to provide a narrow kc way 20 at the outer end, and tho cndsof the orks opcrate above and bolow respective knife-edged )rojections 23 24 on the interior of the combined hollow housing and carrier 25, in WlllCh a part of the actuntorfi is slidable, and which housing amlcarricr is capable under some conditions of a reciprocating and rotative movement in the outer knob and knob-shank. Figs. 4 and 5 show the respective upper and lower coin onents 25 25 of the housing 25. The houseil portion of member 6 has two op- )esitely-extending lateral projections 26, lormin a cross-head which operates in slots 27 in the sides of the housing 25. A spring 28, surrounding the housing, bears a ainstthis cross-head and against a rm 29, w iich is set into and secured to the insi( e of flange 2, and which spring acts to retract the member'fi normally outward to free the cams 18 of any engagement with the bolt 7. The outer end of the housing 25 is closed except for a thin slot 30, registering with the keyway 20 and adapted to receive a thin instrument, as the When the inside knob, to which the-actuator is fixed, is turned to bring the actuator into register with the notches 8 9, the dog 5 being engaged in one or the other of these notches, the inner knob and actuator are held against further rotation, but both may be moved to retract bolt 7 ,first, by pushin the key, passing through the slot 30 into the eyway 20, or, second, by taking hold of knob B and pulling on it, or, thirdly, provided a projection '32 on the housing 25 is in register with a slot 33 in ring 29, by pushin inon the exposed end of the housing 25, whic pushing action carries both the housing and actuator forward. Any one of these three erations will cause a cam 18 to operate on be t 7 to retract the latter. It is understood that notches 8 9 lie not onl in the same plane with the actuator, but wit slot 13 in bolt 7, so that when the actuator is in line with notches 8-9 the actuator-may reci rocate to allow a cam 18 to operate, as descri ed. If it is desired, however, to lock the bolt 7 and the actuator against movement, the dog is depressed and the knob B turned a quarter-tum in the rightdirection to bring the dog into the single shallow notch 11. Then it is impossible to turn either the knob or the actuator or to reciprocate the latter, since the dog prevents rotation and the shoulders 6 of the actuator engage plate 4 and also the cams 18 are brought crosswise of slot 13 and engaged'in notch 34 on the slotted part of bolt 7.

The notches 8 9 11 cooperate to produce each a separate and different result and are disposed 1n a definite relation to the projection 32 on the housing 25 and the slot 33 in rin 29. When the dog is inline with notch 8, or example, the projection 32 is also in restart line with slot 33, and at that time and only then can the housin be moved in to open the door from the outsi e without a key. In all other positions'of the actuator and knob B in their rotation the projection 32 and slot 33 are out of line, and the housing cannot rcci rocate bccauseof the stop provided to the projection 32 by the ring-guide 29. When the dog 5 is in line with notch 9, the actuator may be pushed in by means of a key or other suitable instrumenta -inserted into the keyway or by pulling on knob B; but when the dog is in notch 11 everything is locked against either rotative or reciprocal movement. The distance to which the actuator may be pulled or pushed inwardly is limited by suitable means, as the shoulders '7.

In order to guard a ainst the lock being picked and to provide or a wide range of action in the construction of,the looks, I refer to employ a tumbler-plate -35, dispo ina recess inthe'housing and having projecting-ends 36 slidable and guided in suitable cam-slots 37 inthe walls of the housing. This late has a series of suitably-st reections or pins 38 always engage m 'pe orations 39 in the housed portion of member-6, and which perforations extend across the keyway 20.

Ordinarily with the member fiiretractcd to its outermost limits the plate is lifted, by reason of the upraise in the slots-37, .to retract the pins 38 from the keyway, and so olier no op osition to the insertion of a keg. The pins, owever, are -not entirely 'wit drawn from the holes 39, with the result that any inward movement-of the actuator will carry the plate 35-alo too; but if the he which is inserted into t e ko ay, although it be of the right width and t 'ckness, be not erforated in exact correspondence with the lioles 39 and the-do th of. the keyway the pins 38 by reason 0 the shape of slots 37 will be pressed down so hard on'the key when it is attempted to push in on the actuator that the key will bind and the lock will refuse towork.

The only way to open the look from the outside when set to be operated 'by'the :key alone from that side is to-insert the key clear to the back of the keyway. inasmuch as the pins 38 are so staggeredand so numerous-as to present a practically solidlfront to the eutry of a key or other instrument not having the roper perforations, it is impossible, as has con amply demonstrated in practice, to pick the lock.

'The purpose of theledges 23 24 .is*to shield the outer bifurcated and of the member-*6 from being pushed in by a wire or some such means entered through slot 30.

It is possible that various 'mod'rficationsin my invention may be made without departing'from the principle thereof, and ldo not wish to be understood as'limiting myself to aaai'n the specific construction as herein shown and described.
